Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

Mixing and dispensing curable multi-component materials

A method of providing an easy-clean, water-sheeting coating on a substrate includes: abrading a surface of a substrate using an abrasive article to provide an abraded surface having a surface roughness R?a#191 in a range of from 100 nm to 3500 nm, contacting a coatable composition with the abraded surface, and removing water from the coatable composition. The coatable composition comprises silica nanoparticles and has a pH of 7.5 or less. A kit including the abrasive article and the coatable composition is also disclosed.

Easy-clean surface and method of making the same

Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a pre-determined coating pattern. All three components are generally in registration with each other, thereby providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.

Coated abrasive articles

Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a plurality of discrete islands. The coating pattern has features in which all three components are generally in registration with each other, while providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.

Coated abrasive article and method of making the same

Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a pattern of discrete islands, or features, having an areal density ranging from about 30 features to about 300 features per square centimeter and an average feature diameter ranging from about 0.1 millimeters to about 1.5 millimeters. Optionally, the provided abrasive particles have an average abrasive particle size ranging from about 20 micrometers to about 250 micrometers and the average make layer thickness ranging from 33 percent to 100 percent of the average abrasive particle size. This coating pattern provides that all three components are generally in registration with each other, while also providing a pervasive uncoated area extending across the backing, thereby providing improved cut and finish performance while displaying a resistance to curl in wet environments.

Coated abrasive article

Provided are abrasive articles having a plurality of elongated channels extending across its working surface and intersecting with each other. These channels provide hinge points that enhance flexibility of the article along two or more directions. Optionally, the abrasive article includes a flexible attachment layer, along with apertures that penetrate through the attachment layer located at the intersection points of the channels. The enhanced flexibility allows the abrasive article to easily access recessed areas of the workpiece and facilitates applying even pressure across convex and concave surfaces. The channels assist in segregating dust particles from the abrading operation, and the optional apertures can be advantageously connected to a vacuum source for evacuation of the dust particles from the channels.

The present invention provides a method of cleaning an engine having at least one combustion chamber, and the method includes the steps of providing an engine cleaning composition and introducing the cleaning composition into the combustion chamber. The engine cleaning composition includes: (i) 10-100 wt % of an alkanol amine hydroxy carboxylate represented by formula (I): RCHOHCOONH((CH2)OH)(I), wherein n is an integer in the range of 1 to 10; a is 0, 1 or 2; b is 1, 2 or 3; such that a+b=3; R represents hydrogen atom or alkyl; (ii) 0-90 wt % of a surfactant; (iii) 0-90 wt % of a solvent; and (iv) 0-90 wt % of water. The present invention also provides an engine cleaning composition to remove carbon deposit from engines.

A thermally conductive LED assembly is disclosed. The thermally conductive LED assembly includes an elongate conductor cable having a first conductor and a second conductor extending along a length of the elongate conductor cable and a thermally conducting and electrically insulating polymer layer disposed between first conductor and second conductor and a second electrically insulating polymer layer is disposed on the first conductor or second conductor. The electrically insulating polymer layer having a thermal impedance value in a range from 2.5 to 15 C.&#xb0;-cm2/W and a plurality of light emitting diodes are disposed along the length of the elongate conductor cable. Each light emitting diode is in electrical communication with the first conductor and the second conductor.

The present disclosure relates to a profiled masking article and method of masking a substrate to be treated or painted that provides a feathered or soft edge between painted and unpainted areas. The masking article described herein may be used as a single strip, or as multiple strips, placed side by side, wherein a strip is removed between treatments of different types. This allows successive treatment layers to completely cover previous layers, thus avoiding defects resulting from exposed layers of material. In an embodiment, the present disclosure is directed to a masking article comprising: at least one elongate body (), said body () having a top surface, a bottom surface and at least two lateral surfaces, wherein at least a portion of said body comprises an adhesive material; and a generally planar top portion (), connected to the body along at least one surface, said top portion () having a microstructured surface.

A curable body repair material is described. The curable body repair material includes a curable polymeric resin, and a plurality of hollow elements. The curable body repair includes less than 3% by number of hollow elements having a diameter greater than 100 micrometers. Method of making and using the same are also described.

Hollow element filled curable body repair compounds

A central labeling data (CLD) management system provides centralized management, assembly, and distribution of labeling data for use in generating replacement labels for damaged vehicles. For example, the CLD management system includes a database that stores label data for a plurality of vehicles produced by a plurality of different manufacturers. The CLD management system presents an interface to receive an electronic communication from a client computing device associated with a repair shop. The electronic communication includes a request for label data associated with an original vehicle label. The CLD management system retrieves the requested label data from the database and communicates the label data to an output device for printing a new vehicle label for use by the repair shop.
